Dunno 'bout all that.
Most RATS just shoot 'em with live ammo & forget the dry fire, I'm told.
Some put Wolff springs in. Most don't.
I dunno how a "slicked-up" one would feel.
The more ya work 'em. the better they get.
Reckon I'd put snap caps or cushioned cartridges in afore I dry fired 1000 times, though.
